Intermediate film for laminated glass, and laminated glass

Abstract

The present invention aims to provide an interlayer film for laminated glass capable of displaying images with a high luminous intensity when irradiated with a light beam, and a laminated glass including the interlayer film for laminated glass. The present invention relates to an interlayer film for laminated glass, including a light-emitting layer that contains a thermoplastic resin and a lanthanoid complex with a polydentate ligand containing a halogen atom, the light-emitting layer containing not more than 50 ppm in total of potassium, sodium, and magnesium.

1 . An interlayer film for laminated glass, comprising
 a light-emitting layer containing a thermoplastic resin and a lanthanoid complex with a polydentate ligand containing a halogen atom,   the light-emitting layer containing not more than 50 ppm in total of potassium, sodium, and magnesium.   
     
     
         2 . The interlayer film for laminated glass according to  claim 1 ,
 wherein the lanthanoid complex with a polydentate ligand containing a halogen atom is a lanthanoid complex with a bidentate ligand containing a halogen atom or a lanthanoid complex with a tridentate ligand containing a halogen atom.   
     
     
         3 . The interlayer film for laminated glass according to  claim 1 ,
 wherein the light-emitting layer contains not more than 40 ppm of magnesium.   
     
     
         4 . The interlayer film for laminated glass according to  claim 1 ,
 wherein the halogen atom is a fluorine atom.   
     
     
         5 . The interlayer film for laminated glass according to  claim 1 ,
 wherein the light-emitting layer contains a lanthanoid complex with a bidentate ligand containing a halogen atom and having an acetylacetone skeleton.   
     
     
         6 . A laminated glass comprising:
 two transparent plates; and   the interlayer film for laminated glass according to  claim 1  interposed between the transparent plates.   
     
     
         7 . An interlayer film for laminated glass, comprising:
 a light-emitting layer containing a thermoplastic resin and a lanthanoid complex with a polydentate ligand containing a halogen atom; and   an adhesive layer containing a thermoplastic resin and at least one metal salt selected from the group consisting of alkali metal salts, alkaline earth metal salts, and magnesium salts,   the light-emitting layer containing a smaller total amount of alkali metals, alkaline-earth metals, and magnesium than the adhesive layer.   
     
     
         8 . The interlayer film for laminated glass according to  claim 7 ,
 wherein the lanthanoid complex with a polydentate ligand containing a halogen atom is a lanthanoid complex with a bidentate ligand containing a halogen atom or a lanthanoid complex with a tridentate ligand containing a halogen atom.   
     
     
         9 . The interlayer film for laminated glass according to  claim 8 ,
 wherein the total amount of sodium, potassium, and magnesium in the light-emitting layer is smaller than the total amount of sodium, potassium, and magnesium in the adhesive layer.   
     
     
         10 . The interlayer film for laminated glass according to  claim 8 ,
 wherein the light-emitting layer contains not more than 40 ppm of magnesium.   
     
     
         11 . The interlayer film for laminated glass according to  claim 8 ,
 wherein the halogen atom is a fluorine atom.   
     
     
         12 . The interlayer film for laminated glass according to  claim 8 ,
 wherein the light-emitting layer contains a lanthanoid complex with a bidentate ligand containing a halogen atom and having an acetylacetone skeleton.   
     
     
         13 . A laminated glass comprising:
 two transparent plates; and   the interlayer film for laminated glass according to  claim 8  interposed between the transparent plates.
